/* Permutation (system entry) game page.
   (Controllers/GamesController.cs, Views/Games/Permutation.cshtml)

   Loads alongside predict.css purely for the shared top bar, which is keyed on
   body:has(.predict-shell). Nothing else on the site reads this file.

   The result list is a grid rather than a <table>: a 6-digit entry renders 360
   rows, and a grid of divs keeps the markup per row down to what is actually
   needed. Prize badges reuse .history-position-badge / .pos-* from site.css so
   they match the past-result search. */
